FMRI Studies of Visual Categorization in The Human Brain
Alexander Huth, et.al., at the University of California, Berkeley, have demonstrated how five human subjects, each viewing over two hours of movie clips, were each scanned by functional Magnetic Resonance Imaging instruments. Each brain scan recorded blood flow in thousands of individual locations, across their respective brains. Principal components analysis of regularized linear regressions revealed 1700 visual categories of 30,000 locations in cortex. Huth et.al. found highly organized, overlapping maps that occupied over 20% of cortex.

“You must train the children to their studies in a playful manner, and without any air of constraint, with the further object of discerning more readily the natural bent of their respective characters.”
—Plato (c. 427–347 B.C.)
“To write well, to have style ... is to paint. The master faculty of style is therefore the visual memory. If a writer does not see what he describes—countrysides and figures, movements and gestures—how could he have a style, that is originality?”
—Rémy De Gourmont (1858–1915)
“We are naïve and moralistic women. We are human beings. Who find politics a blight upon the human condition. And do not know how one copes with it except through politics.”
—Kate Millett (b. 1934)
“Progress celebrates Pyrrhic victories over nature. Progress makes purses out of human skin. When people were traveling in mail coaches, the world got ahead better than it does now that salesmen fly through the air. What good is speed if the brain has oozed out on the way? How will the heirs of this age be taught the most basic motions that are necessary to activate the most complicated machines? Nature can rely on progress; it will avenge it for the outrage it has perpetrated on it.”
—Karl Kraus (1874–1936)
